 Cavity Detection Tool (CADET) is a machine learning pipeline trained to detect X-ray cavities from noisy Chandra images of early-type galaxies. <br>\
 To use this tool: upload your image, select the scale of interest, make a prediction, and decompose it into individual cavities! <br>\
 Input images should be in units of counts, centred at the galaxy center, and point sources should be filled with surrounding background ([dmfilth](https://cxc.cfa.harvard.edu/ciao/ahelp/dmfilth.html)). <br>\
